Description

Technical Field

[0001] This invention relates to the field of bicycle technology, and more particularly to a handlebar and a bicycle. Background Technology

[0002] With modernization, people's activity radius is expanding, and there are more and more fast, high-capacity transportation tools such as cars, buses, and subways. However, the downside is that driving leads to increasing urban congestion and parking difficulties. When taking public transportation, there are often distances of one to several kilometers between home and work and bus or subway stations. Currently, bicycles and electric bicycles are inconvenient to carry around, and if you ride a bicycle to both ends, their storage and theft prevention become problems. Walking usually takes ten to several tens of minutes, which is not only tiring but also wastes a lot of time. Therefore, people hope to have bicycles or electric bicycles that can be folded and carried with them.

[0003] In folding bicycles, the handlebars are a relatively large component. In traditional folding bicycles, the handlebars can hardly be folded, or only the head tube of the handlebars can be folded to the side.

[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects and not to describe a particular order.

[0048] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0049] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] Reference Figures 1 to 10 This invention proposes a handle, comprising: a head tube 1, a V-shaped connector 2, a left handlebar 3, and a right handlebar 4; wherein,

[0051] V-type connector 2 is connected to the top of the head tube 1. The V-type connector 2 has a first connection port 21 and a second connection port 22 that are angled downwards.

[0052] The left handle 3 is movably connected to the first connection port 21, and the left handle 3 can rotate around the first connection port 21 with the axis of the first connection port 21 as the central axis; the right handle 4 is movably connected to the second connection port 22, and the right handle 4 can rotate around the second connection port 22 with the axis of the second connection port 22 as the central axis.

[0053] Both the left handlebar 3 and the right handlebar 4 have a used position and a folded position. When both the left handlebar 3 and the right handlebar 4 are in the used position, the left handlebar 3, the right handlebar 4 and the head tube 1 form a "Y" shape. When both the left handlebar 3 and the right handlebar 4 are in the folded position, the left handlebar 3 and the right handlebar 4 are parallel to the head tube 1.

[0054] In this embodiment, the left handlebar 3 and right handlebar 4 are generally elongated. To facilitate folding and storage, the left handlebar 3 and right handlebar 4 are designed to be nearly straight. Some curvature or small-curve bends can be incorporated as needed. For example, in embodiments where the handlebars are relatively compact, both the left handlebar 3 and right handlebar 4 can have a section whose length does not exceed 35% of the overall length and whose curvature does not exceed 35°. This allows the left handlebar 3 and right handlebar 4 to have a larger overall angle during use, meaning the "Y" shape opens more widely. This also increases the lever arm for controlling the handlebars, making them easier to operate and more ergonomic. To facilitate connection to the V-connector 2, a structure such as a short connector can be connected first, and then the V-connector 2 can be connected through these short connectors, as shown in the first connector 31 and second connector 41 described later.

[0055] In one embodiment, the left handle 3 is provided with a first connector 31 at one end and the right handle 4 is provided with a second connector 41 at one end; the first connection port 21 has a first snap-fit ​​position and a second snap-fit ​​position, and the first connection port 21 has a third snap-fit ​​position and a fourth snap-fit ​​position.

[0056] When both the left handle 3 and the right handle 4 are in the use position, the first connector 31 connects to the first connection port 21 and is locked in the first locking position, and the second connector 41 connects to the second connection port 22 and is locked in the third locking position; when both the left handle 3 and the right handle 4 are in the folded position, the first connector 31 connects to the first connection port 21 and is locked in the second locking position, and the second connector 41 connects to the second connection port 22 and is locked in the fourth locking position.

[0057] In this embodiment, the aforementioned "use state position" and "folded state position" refer to the two fixed positions of the left handlebar 3 and the right handlebar 4. The use state position corresponds to the position of the left handlebar 3 and the right handlebar 4 when riding, and the folded state position corresponds to the position of the left handlebar 3 and the right handlebar 4 when folded and stored. The first connector 31 and the first connecting port 21 can be in the form of threaded connection, socket connection, etc. For example, the first connector 31 is threaded to the first connecting port 21, and the second connector 41 is threaded to the first connecting port 21. When both the left handlebar 3 and the right handlebar 4 are in the use state position, the rotation position of the left handlebar 3 can be limited by a limiting structure such as a screw passing through the first connector 31 and the first connecting port 21 from the side wall. At this time, the first snap-fit ​​position is the position where the screw hole on the first connector 31 and the screw hole on the first connecting port 21 are aligned. After the limiting, the first connector 31 and the first connecting port 21 are snapped by the screw, and the left handlebar 3 can no longer rotate, that is, the left handlebar 3 is fixed in the use state position. Similarly, the right handlebar 4 is fixed in a similar way, which will not be described in detail.

[0058] In one embodiment, the left handle 3 further includes: a first limiting ring 32 and a first limiting screw 33; the right handle 4 further includes: a second limiting ring 42 and a second limiting screw 43; wherein...

[0059] The first connector 31 has a pair of first openings 311 on its side wall, which pass through the opposite side from one side; the second connector 41 has a pair of second openings 411 on its side wall, which pass through the opposite side from one side; the first locking position is a pair of first limiting notches 211 on the side wall of the first connection port 21; the second locking position is a pair of second limiting notches 212 on the side wall of the first connection port 21; the third locking position is a pair of third limiting notches 221 on the side wall of the second connection port 22; and the fourth locking position is a pair of fourth limiting notches 222 on the side wall of the second connection port 22.

[0060] The first limiting screw 33 is inserted from one side of the first limiting ring 32, passes through the first opening 311 and is fixed to the other side of the first limiting ring 32, so that the first limiting ring 32 is sleeved on the first connector 31. The second limiting screw 43 is inserted from one side of the second limiting ring 42, passes through the second opening 411 and is fixed to the other side of the second limiting ring 42, so that the second limiting ring 42 is sleeved on the second connector 41.

[0061] When both the left handle 3 and the right handle 4 are in the working position, the first opening 311 corresponds to the first limiting notch 211, the first limiting ring 32 is engaged with the outside of the first connecting port 21, and the first limiting screw 33 is engaged with the first limiting notch 211; the second opening 411 corresponds to the third limiting notch 221, the second limiting ring 42 is engaged with the outside of the second connecting port 22, and the second limiting screw 43 is engaged with the third limiting notch 221; when both the left handle 3 and the right handle 4 are in the folded position, the first opening 311 corresponds to the second limiting notch 212, the first limiting ring 32 is engaged with the outside of the first connecting port 21, and the first limiting screw 33 is engaged with the second limiting notch 212; the second opening 411 corresponds to the fourth limiting notch 222, the second limiting ring 42 is engaged with the outside of the second connecting port 22, and the second limiting screw 43 is engaged with the fourth limiting notch 222.

[0062] In this embodiment, the left handle 3 is used as an example for explanation: The first opening 311 is a pair of openings with the axis of the first connector 31 as the axis of symmetry. The first limiting screw 33 can slide left and right within the first opening 311, which is equivalent to the first opening 311 forming a groove for the first limiting screw 33. External force, such as the user's hand, can be used to move the first limiting screw 33 left and right within the first opening 311, allowing it to slide left and right. When the left handle 3 needs to be fixed in the use position, simply insert the first connector 31 of the left handle 3 into the first connection port 21 in the use position. At this time, the side of the first opening 311 near the first limiting notch 211 is aligned with the first limiting notch 211. Then, the first limiting screw 33 is moved onto the first limiting notch 211 for engagement, thus fixing the left handle 3. It is worth mentioning that the first limiting screw 33 can be connected to the first limiting notch 211 by interference fit, or, as described in subsequent embodiments, by a spring for auxiliary connection. During disassembly, simply pull the first limiting screw 33 out of the first limiting notch 211, and the left handle 3 can be rotated and stored. The principle for fixing the left handle 3 in the folded position is similar to the above, and will not be repeated here. Similarly, the principle for fixing and disassembling the right handle 4 in both the use and folded positions is similar to that of the left handle 3, and will not be repeated here. Furthermore, the first limiting notch 211 and the second limiting notch 212 can be arranged adjacent to each other, that is, the second limiting notch 212 is next to the first limiting notch 211, as shown in the attached figure. Figure 9 As shown, in this configuration, the left handlebar 3 is tilted slightly forward, allowing the user to extend their hand forward to operate the handlebar. This allows the entire vehicle to be made smaller, and the tilting effect can be achieved as shown in the attached diagram. Figure 2 As shown.

[0063] In one embodiment, the left handle 3 further includes a first spring 34; the right handle 4 further includes a second spring 44; wherein...

[0064] The first connector 31 is provided with a first limiting hook 312 inside, and one end of the first spring 34 is connected to the first limiting hook 312, and the other end is connected to the first limiting screw 33.

[0065] The second connector 41 is provided with a second limiting hook 412 inside. One end of the second spring 44 is connected to the second limiting hook 412, and the other end is connected to the second limiting screw 43.

[0066] In this embodiment, the left handlebar 3 is used as an example for explanation. The structure of the right handlebar 4 is symmetrical to that of the left handlebar 3, and the same principle applies. The first connector 31 is a tubular connector, which can accommodate the brake cable passing through it. The first limiting hook 312 is arranged inside the first connector 31 and near the opening of the first connector 31. The first opening 311 is arranged further inside the first connector 31 than the first limiting hook 312. Thus, when one end of the first spring 34 is connected to the first limiting hook 312 and the other end is connected to the first limiting screw 33, the first spring 34 is in a stretched state and can always generate an elastic force to pull the first limiting screw 33 towards the first limiting hook 312. Since the first connector 31 is inserted into the first connecting port 21 for connection, during connection, the first limiting hook 312 is located inside the first limiting notch 211, that is, it always generates a pulling force to hold the first limiting screw 33 on the first limiting notch 211, preventing the first limiting screw 33 from disengaging from the first limiting notch 211. The situation where the first limiting screw 33 connects to the second limiting notch 212 is similar to that described above, and will not be repeated here.

[0067] In one embodiment, the left handle 3 further includes: a first main rod 35 and a first connecting rod 36; the right handle 4 further includes: a second main rod 45 and a second connecting rod 46; wherein...

[0068] The first connecting rod 36 is connected to the first main rod 35 at one end and to the first connector 31 at the other end; the second connecting rod 46 is connected to the second main rod 45 at one end and to the second connector 41 at the other end; when the left handlebar 3 and the right handlebar 4 are both in the folded position, the first main rod 35 and the second main rod 45 are both parallel to the head tube 1.

[0069] In this embodiment, the first main rod 35 is the main body of the left handlebar 3, and its length accounts for the majority of the entire left handlebar 3. For example, the length of the first main rod 35 is 2-5 times the length of the first connecting rod 36. The first connecting rod 36 is provided to increase the angle between the left handlebar 3 and the right handlebar 4, making the lever arm larger and easier for the user to operate. In some embodiments, a brake can be provided at the end of the first main rod 35. To facilitate the routing of the brake cable, both the first main rod 35 and the first connecting rod 36 can be tubular, with the brake cable arranged internally. The first connecting rod 36 can be a single section of round tube connected to the first main rod 35 by means of threaded connection, welding, etc. Alternatively, the first main rod 35 and the first connecting rod 36 can be the same straight tube, which can be slightly bent, such as by bending it at 150° or 160°.

[0070] Or 170°, etc. After bending, the longer section becomes the first main rod 35, and the shorter section becomes the first connecting rod 36. Specifically, make a 155° bend at 1 / 4 of the length of the straight pipe.

[0071] In one embodiment, the supplementary angle of the angle formed between the first main rod 35 and the first connecting rod 36 is α1, the angle between the first connecting rod 36 and the first joint 31 is β1, and the angle between the axis of the first connecting port 21 and the head tube 1 is γ1; the relationship between α1, β1 and γ1 satisfies: α1+β1+γ1=180°;

[0072] The supplementary angle between the second main rod 45 and the second connecting rod 46 is α2, the angle between the second connecting rod 46 and the second joint 41 is β2, and the angle between the axis of the second connecting port 22 and the head tube 1 is γ2; the relationship between α2, β2 and γ2 satisfies: α2+β2+γ2=180°.

[0073] In this embodiment, on the left handle 3 side, the relationship between α1, β1 and γ1 satisfies: α1+β1+γ1=180°, which enables the first main rod 35 to be parallel to the head tube 1 after folding. On the right handle 4 side, the relationship between α2, β2 and γ2 satisfies: α2+β2+γ2=180°, which enables the second main rod 45 to be parallel to the head tube 1 after folding.

[0074] In one embodiment, the head tube 1 includes an upper head tube 11 and a lower head tube 12, which are movably connected, and a V-shaped connector 2 is connected to the upper head tube 11.

[0075] In this embodiment, the head tube 1 is configured as two sections, namely the upper head tube 11 and the lower head tube 12. The upper head tube 11 and the lower head tube 12 are movably connected, which can reduce the length after folding and help to reduce the volume after folding. After being stored, the overall length of the upper head tube 11 and the lower head tube 12 is basically the same as the length of the left handle 3, that is, it is also basically the same as the length of the right handle 4.

[0076] In one embodiment, the head tube 1 further includes: a quick-release locking ring 131, a quick-release clamping screw 132, a first anti-rotation screw 133, a wear-resistant washer 134, a quick-release pull rod 135, a pull rod connecting shaft 136, a quick-release wrench 137, and a second anti-rotation screw 138; wherein...

[0077] The upper head tube 11 is provided with a limiting groove arranged along its length direction. The top end of the lower head tube 12 is provided with a limiting hole and a tightening groove. The upper head tube 11 is inserted into the lower head tube 12. The quick-release locking ring 131 is sleeved on the top end of the lower head tube 12. The first anti-rotation screw 133 passes through the quick-release locking ring 131 and abuts against the limiting groove. One end of the quick-release pull rod 135 is connected to the quick-release clamping screw 132, and the other end passes through the two directional holes of the quick-release locking ring 131 in sequence, and then passes through the wear-resistant washer 134 to connect to the pull rod connecting shaft 136. The pull rod connecting shaft 136 is set at one end of the quick-release wrench 137 through the second anti-rotation screw 138.

[0078] In this embodiment, the quick-release locking ring 131, quick-release clamping screw 132, first anti-rotation screw 133, wear-resistant washer 134, quick-release pull rod 135, pull rod connecting shaft 136, quick-release wrench 137 and second anti-rotation screw 138 constitute quick-release lock 13. By controlling the quick-release pull rod 135, the tightness of the quick-release locking ring 131 can be controlled to clamp and fix the connection between the upper head tube 11 and the lower connector tube, or to loosen the connection.

[0079] In one embodiment, the handlebars also include a downtube connector 14, which is threadedly connected to the downtube 12. The downtube connector 14 has an inclined structure 141 at the bottom, and the inclined structure 141 has a connecting block 142 and a through hole 143 for passing through the downtube 12. The connecting block 142 is provided with a shaft hole 144; the shaft hole 144 is used for movably connecting the bicycle frame.

[0080] In this embodiment, the handlebar also includes a lower tube connector 14, which has a through hole 143 through which the oil pipe 5 can pass. The lower tube connector 14 is used to connect to the vehicle body and can also be fixed by a limiting sleeve 6.
